4 Claims. (Cl. 120-145) :Our invention relates to a pencil which can be used to write in any of a number of colors, at the will of the user. Heret'ofore, pencils have been constructed to write in more than one color, but in general they have [been bulky, difiicult to operate, easil damaged, andexpensive to manufacture.

It, therefore, is an object of our invention to provide a" pencil capable of writing in a wide range of colors," and which is slender, sturdy, easily manipulated, and of inexpensive construction.

Another object of our invention is to provide a single pencilof the character described which can substitute-for a box of colored crayons.

Another object of our invention is to provide a selective, multi-color pencil which is easily reloaded, and which provides an indication of the color in use, and of the other colors available.

Other objects of our invention are to provide an improved device of thecharacter described, that is-easily and economically produced, which is sturdy in construction, andwhich is highly efiicient-in operation.

With" the above and related objects in view, our invention consists inthe details of construction and combination of parts, as will be more fully understood from the following description, when-read in conjunction with the accompanying drawing inwhich:

Fig-l3 is a partly sectional side view showing the operating slidein engagement with a carrier, with the carrier partly extended.

Referring now to the drawings, wherein the same reference characters designate the same parts, we show a pencil, consisting of a barrel,

generally designated as A, a hood, generally designated as B, a revolvable chamber, generally designated as D, an operating slide, designated as E, a plurality of colored-lead carriers, each designated as F, a color index cap G, and a barrel head, designated as H. i I The lead carriers F, one of which is illustrated in Fig. 6, are long narrow members made of flat stock having a short extension l6 ofiset at one end. The otherend [8 which is broader than the body of the carrier has a small slot 20 whose walls cooperate with a shoulder 2| on the barrel head H,as will be described presently. A short piece of flexible tubing 22 is supported upon the onset end It of each carrier, and the tubing in turn receives and supports a single colored lead 24.

As shown in Figs. 7 and 11, the carriers F, when not extended for use, lie substantially within longitudinal slots26 of the revolvable cylinder D. The cylinder D comprises a long, cylindrical member having a central bore 28 and a plurality of longitudinal slots 26 which extend from one end}: of the chamber to the other end 30. The bore 28 is reduced in diameter for a short length 3l'at the end iii! of the chamber to lock with the 'endtii ofthe shaft 34. The slots 26 are of a width sunicient to accommodate the lead carriers F already described.

The cylinder D, the barrel head H, and the coloredindex cap G are mounted upon the shaft 34; however, the barrel head II and the colored t index cap G are rigidly attached to rotate in unison 'with' the shaft while the cylinder D- has relatively free rotation about the shaft. The cylinder D and its barrel A rotate in unison. The

operating slide E also rotates about the shaft 34 but it is controlled to rotate when it is in the narrow slot in the barrel head H.

The cylinder D comprises a, cylinder having a V series of equally spaced chambers 26 extending Way along the longitudinal axi of the cylinder the slots 26 become shallow so that a lead carrier may rest in the slot. The operating slide is adapted to move within the completely slotted end of the cylinder D in order to push the lead carrier F along the chamber 26 in which it is nestled.

As shown in Fig. 10, a slender metal shaft 34 extends through the bore 28 of the. chamber D and is firmly. attached at one end 38'to the length SI of the chamber.

slots 26.

colors of lead carried in the correspondin'g'ch'am= ber slots 26. knurling 44, to facilitate the rotation of the cap by; the user, and the cap mayalso be adapted to hold an eraser 46. v

As-show-rr-in Figs. 4 and 5, a cylindrical barrel head- H is rotatably mounted .on the axial shaft 34, between the color index cap, G, and the open end-29 of therevolvable cylinder D. That portion lz of the .barrel head which is adjacent to the cylinder is reduced in diameter, andis providedwith an annular shoulder H at its extremity. a 7

As shown in.-Fig. 11,. when a lead carrier F lies withina cylinder. slot. 25; in retracted position, the'shoulder 2| of the barrel .head is seated within the slot ZQ-of the carrier.

As shown inFigs. lland 13, the barrel head His provided with a bore- 48.Which extends approximately half the length of the barrel head,- commencing from the shoulder end thereof. The wallwhich bounds the bore 38 has a single longitudinal: slot 59 The slotiifl and the bore 48 are adapted .to accommodate the. c shaped operatingslideE. A short pin 52 isfixedin the solidzportion of the barrelhead, and this pin helps to lock the barrel head H to the barrel A. aswillbe. described later. 7

Theoperating slide E, shown in Fig. 5, consists of-:a-.G-.shaped member with a cylindrical bottom 63, ..which bottom encirclesthe axialshaft 3 1. The'rlower horn Sit-of the operating slide. has the same outline asthe section of the. shoulder 21, as-illustrated Figs. lQand .12. The aperture enclosed bythe C-shaped Inember E forms an ye, l6, in which awedge member operates, as Willbt? described later. a

As show n in Figs. 2 and '7, the barrel A of the pencil comprises a long hollow cylindrical member; which member is externally threadedat one end 5 l-.to secure the hood B thereto. Along narrow slot '56 is located in the Wall of the barrel A, and. this .slot. extends from the unthreaded endof the barrel along the greater part of the barrels length and is .open at the other end.

As shown in Fig. 3, the hood B of the pencil has a cylindrical end 68 which is internally threaded to screw upon the threaded end 54 of theibarrel, andfrom the cylindrical. end 60 the hood B tapersconically .as at 6| to a small round aperture 62 through which aperture the writing lead projects. Since the pencil of our invention is refilled with new leads 24 from the point end of'the barrel, thev hood B is adapted to be easily unscrewedfrom the barrel. Knurlinglfit'is providedon the hood for this purpose.

The.assemblyof the. parts and their functioning .is-as follows:

The axial shaft 34 serves as a mounting upon The other end 38 of the shaft is rigidly attached to the color index cap G.. The color index cap G has a number ofdepres-v sions All spaced around the circumferencethereof, equal in number and alignedLWithmthe(chamber These depressions 40 are filled w-ith various colors which colors mayindicate the The cap G is also proviidd-with which are located the rigidly secured color index cap G, the rotatable barrel head H, the movable operating slide E, and the rigidly secured chamber D. The operating slide may be introduced into the barrel head slot 50, in which location it remains together with the barrel head when shaft 34 is revolved. In addition, when the barrelhead slot 50 is aligned with any particular chamber. slot 26; .the lower horn 64 of the operating slide E becomes engaged with the carrier F lying in that particular slot. The operatin slide may then be moved longitudinally along'the chamber slot 26 so as to extend the y- :carrien: The-aforementioned action is illustrated ziII'EiES. 10, 11, 12 and. 13.

A. lead .carrier F is located in each chamber '"slotitj eachca'rrier having its slot 20 engaged bygtlieshoulder 2| of the barrel head. Each carrier supports a single colored lead by means of ashort piece. of..fiexib1e tubing 12. ,One end of thetu-bihgslipped upon theextension'l 6' of the lead carrier and the otherj'efid'fof. theitubin'g is slipped-...over .anendof tlie cOlbredQeadZt. Since --the. offsetv extension IG'bf' the carrier is directed toward the longitudinal. axis of the pencil, the leadsiZ i are but. slightlidisplaced from this axis;v as shown Fig'SL" 'Whena -lead carrier. is extendedlthe leaded. 'is guidedbvthe conical wallf'fill'of the. tip'. hood through the cen-- tral: aperturelfi ijith flexible tubing. 22"bending as required.

When the described subassembly is inserted with the barrel A, the operating'fslide E projects through the. longitudinal slot 58 in the barrel. In: addition, the. fixed. pin 52in the barrel head projects..into .a. circular emarge'ment T5? of the slot-5%. A .metalretaining. band J 'fits tightly over. the cap endoflthe.barreLlockingthe barrel slot and the pinfiZ. in-'- engagement. 'An index mark ES-is provided onthe band J which mark should be :aligned with the slot-5i} in the barrel head when the bandis afiixed-over the barrel.

As shown in Fig. '7, a wedge member 0 is provided on theexterior ofthe barrel A for the purposezofllocleingthe carrier; in position. when the desiredlength,ofthe-colored lead tip is exposed. The wedge. consistsrof a short section it of a ring;:..the.outer;: circumference -12. of: which section is eccentric with the inner.:circumference Hi. This -ringsectionlil extends: through the eye 76 contained by the exposediportionzof: the .Q-shaped operating slide,-.z and; the: ring -.section is provided w-itlrasm'allblock' T8 at each end'to prevent the loss of the wedge. When the wedge C.is.revolvedabout the bar relin thapropendirection, clockwise as--viewed hr-Fig. 7, .the. enlargement of the ring section causes the wedge-to--:clamp against the- 'ba'rrely andagainstthe :t'op ofthe eye?li of theoperatingslide' E, locking the carrier at that point. To release the carrier-,-'the wedge is--rotated--inthe opposite d-irectiom whereupon the" enlarged portibn of the wedge isr-removed from=-engagement-with the barrel and theoperating slide.

' To preparethepencil for writing with any desired color of lead contained inthe-pencil, -the userrotates-the color in'dex cap=G until the depression ii which bears'the-'desired =color---is in registry with"the "index"mark' onthe-ba-nd; The operating slide is" then" moved" toward-'- the-point end of the pencil, the slide traveling within the selected slot'of the cylinder, until the lead projects. from" the; tip aperture'the desired length. The operating slide'is then looked" at this position, using the wedge for the purpose in the manner described.

To reload the pencil, the hood B is removed, the empty carrier F is extended and a new length of colored lead is inserted in the tubing support.

Although we have shown the pencil as having a structure for receiving and writing with six differently colored leads, it is obvious that the pencil might be constructed to contain more or fewer leads as wished.

Although our invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

We claim as our invention:

1. In a multi-color pencil having a plurality of lead carriers, a barrel, a cylinder within said barrel, a shaft about which said cylinder rotates, an operating slide having an eye encircling said shaft and movable along said shaft, said cylinder having a plurality of chambers each of which receives a slide for holding a length of lead, a color index cap, a barrel head, said cap and said barrel head being rigidly attached to said shaft, said operating slide enveloping said metal shaft whereby said slide may move one of said lead carriers, and said cap and barrel head being adapted to rotate said slide whereby one slide may be moved along its complementary chamber.

2. The invention of claim 1 including means to lock said operating slide in a predetermined position.

3. The invention of claim 1 including wedge means for locking said operating slide at any desired degree of extension.

4. A multi-color pencil, comprising a barrel, a point hood, a cap and a shaft revolvable axially in unison within said barrel, a cylinder aflixed to said shaft and free to rotate about said shaft, a plurality of lead carriers, means in said cylinder for receiving said carriers, a single operating slide movably mounted upon said shaft and being adapted to optionally engage only one of said lead carriers, means for indicating the particular lead carrier in engagement with said operating slide at any time, and wedge means for locking said operating slide to said barrel at any point within the travel of said operating slide.
